I have one in the E82 128. Proactively replaced when I did the water pump around 30k miles back. It’s been rock solid. Nice peace of mind for daughter to and from college. About 500 miles one way.

Shes been to and from neighboring cities within a couple hundred miles. With cooling as the weakest link on these things, it’s difficult to go overboard.

 

I just sent the same message out in a Z4 owners group on facebook, someone mentioned they installed one on their LS swapped z4 and has held up great the past 3 years. im thinking the fitment issues must be with E46 owners that have the mechanical fan since i think the bottom plastic bracket cant be installed due to the radiator thickness change. i think that plastic bracket helps hold the fan against the radiator so that wind doesnt blow it back into the accessory belt. the Z4 does have a structural member in between which would probably hold up better.

 

I ended up buying the CSF aluminum radiator, i just got the old radiator out and realized there is no bracket this radiator sits on, its all just held down to the A/C condenser and the condenser has legs on the sides.

 

one thing to keep in mind if you go with the CSF setup the radiator sits a little higher in the location which makes the cover on top not go on easily.

 

Installed the CSF radiator last year on a 2007 e86. It functions great, a bit of a tight fit. Need the Power flex relocation rubber bushings sold at Bimmerworld to move forward at the bottom.

 

I haven’t had an issue with the csf radiator clearance and the expansion with the serpentine belt. Does this help with clearance up top?

 

Correct, N52 in 2007 e86
